Singing "Raptors" Addendum

Fans of vocalizing (non-ornithothoracine) dinosaurs, rejoice! There is still a ray of hope. According to a new comment Dr. Naish has just made on my post about dinosaur vocalization, it turns out that neornithines also use the larynx for vocalization in addition to the syrinx (contrary to older studies), meaning that the common ancestor of crocodilians and neornithines probably had some form of laryngeal vocalization. So non-ornithothoracine dinos may have been able to vocalize after all.
